OpenAPI not generated with MVC API managed by Spring.

[composite]

jooby:openAPI is not caught the MVC API managed by Spring.

I'm made a project with jooby 2.10.0, spring boot 2.5.3, and gradle.

Sample project:
jooby-spring-openapi.zip

App.java

public class App extends Jooby {

  {
    install(new SpringModule());
    install(new OpenAPIModule());
  }

  public static void main(final String[] args) {
    runApp(args, App::new);
  }

}

controller/HomeController.java

@Controller
@Path("/")
public class HomeController {

    @GET
    public String hello() {
        return "HELLO!";
    }

}

jooby:openAPI log

App.json

{
  "openapi" : "3.0.1",
  ...
  "paths" : { }
}

There is no paths generated in openapi json.

This is because the OpenAPI plugin uses ASM to parse the main Jooby to find all the controllers.

@jknack Since OpenAPI is usually MVC maybe the OpenAPI plugin could look at the META-INF services to find the bytecode generated MVC modules.

A workaround is to just to make a fake Jooby with all of your controllers installed and have the OpenAPI plugin use that.
